Fix warning when building `PhoenixCrypto` module

[dpad85]

warning: Building targets in manual order is deprecated - check "Parallelize build 
for command-line builds" in the project editor, or set DISABLE_MANUAL_TARGET_ORDER_BUILD_WARNING 
in any of the targets in the current build to suppress this warning

warning: Run script build phase 'Copy PhoenixCrypto-Swift.h' will be run during every build 
because it does not specify any outputs. To address this warning, either add output dependencies 
to the script phase, or configure it to run in every build by unchecking "Based on dependency 
analysis" in the script phase. (in target 'PhoenixCrypto' from project 'PhoenixCrypto')

Is this still an issue or can we close this?
